Randall Munroe's xkcd comic today is a chart showing the relative depths of lakes and ocean features. It's best seen at full size. In the small detail shown here, the bow and stern belong to the Titanic. What surprised me the most was the depth of the Deepwater Horizon oil well. Also, check out what James Cameron found in his recent trip to the Challenger Deep. Hover over the original comic for the punchline. Link -via Laughing Squid
